Frequently asked questions
What does BMI mean?
The body mass index is a key indicator that is calculated based on the body weight in connection with the body height (body weight divided by body height in centimetres squared).

The BMI is only a reference value to determine the weight category (normal weight, underweight, overweight). Additional factors, e.g. age and gender, must be added for an enhanced interpretation.
